This book, according to the author, presents "quantitative studies on tissue immunity... carried out during a period exceeding five years." Later the author says, "The incompleteness of many of the experiments presented in this volume has been a source of great concern to us." The latter statement should be borne in mind when one evaluates the book, because of its speculative nature and the sweeping generalizations drawn from admittedly incomplete experiments.
A detailed review is impossible because of the size of the volume; only its general plan, therefore, will be described. The author begins with the assumption that relatively little is known about the rôle of the tissues in immunity; from this assumption he proceeds to the hypothesis that tissue immunity is "an inherent physiologic function of all cells." From this idea he develops his thesis that immune tissues, because of their affinity for antigenic substances, constitute the primary basis
